nΩ = pΩ × 0.001
About Picoohms
The picoohm (pΩ) equals 10⁻¹² Ω, used for ultra-low resistance measurements in superconductors and precision four-wire metrology. A superconducting wire transitioning through its critical temperature shows residual resistance at the picoohm level; high-precision Josephson-array resistance bridges operated at national metrology institutes resolve differences below 1 pΩ. 1 pΩ = 10⁻³ nΩ = 10⁻¹² Ω.
About Nanoohms
The nanoohm (nΩ) equals 10⁻⁹ Ω, the same magnitude as the CGS-EMU abohm (1 abΩ = 10⁻⁹ Ω exactly). This scale is used for the lowest measurable resistances in copper busbars at cryogenic temperatures and in precision four-wire measurements of welded or crimped joints; the residual resistance of a high-quality solder joint on 2.5 mm² copper cable falls below 10 nΩ. 1 nΩ = 10⁻³ µΩ = 10⁻⁹ Ω.
